ABSTRACT
Objective To study the relationship between X-linked inhibitor of apoptosis protein (XIAP) expression and transitional cell carcinoma(TCC) development. Methods Forty-three TCC tissues and 12 normal transitional epithelial tissues were applied to detect XIAP expression by semi-quantitative RT-PCR, immunohistochemistry and western blot. The data were statistically analyzed by using SPSS11.5 according to the 2 groups (TCC and normal transitional epithelial) as well as the dif-ferent subgroups (tumor stage, grade, single or multiple tumor, primary or recurrence tumor). Results XIAP expression in TCC tissues was higher than in normal transitional epithelial tissues(im-munohistochemistry: 22±5 and 16±2, Western blot:1.21±0. 15 and 0. 61±0.24, mRNA: 1.17± 0. 30 and 0. 75±0. 17, P<0. 05). In the bladder tumors group, XIAP expression in recurrence tumors was higher than in primary tumors(immunohistochemistry: 24±3 and 20±3, Western blot: 1.66±0.28 and 1.10±0. 23, mRNA: 1.44±0. 27 and 1.05±0. 23, P<0. 05). However, there were no significant differences according to the tumor stage and tumor grade as well as tumor multi-plicity or not. Conclusion XIAP expression might serve as a biomarker in TCC diagnosis and recur-rence prediction.
